In this learning assessment, students demonstrate understanding of the following concepts: solids, liquids and gases, changes of state, convection, and density. Students create a skit where the actors and actresses are molecules, and dramatize,...(View More) through body motions, how the behavior of molecules results in the observable changes we see. A detailed scoring rubric is included with the resource. The investigation supports material presented in chapter 3 "What Heats the Earth's Interior?" in the textbook, Energy flow, part of Global System Science, an interdisciplinary course for high school students that emphasizes how scientists from a wide variety of fields work together to understand significant problems of global impact.(View Less)

This is an activity about magnetic induction. Learners will induce a flow of electricity in a wire using a moving bar magnet and measure this flow using a galvanometer, or Am meter. Through discussion, this activity can then be related to magnetic...(View More) fields in nature. This activity requires use of a galvanometer, bar or cow magnet, and wire. This is the fifth lesson in the second session of the Exploring Magnetism teacher guide.(View Less)

This is an activity about electromagnetism. Learners will set up a simple circuit using a battery, wire, and knife switch, and then use a compass to map the magnetic field lines surrounding the wire. Next, they will add a coil of wire to the simple...(View More) circuit and map the magnetic fields again. This is the second lesson in the second session of the Exploring Magnetism teachers guide.(View Less)

This is an activity about electromagnetism. Learners will use a simple circuit powered by a battery source to investigate the strength of the magnetic field produced by a coil of wire in the circuit. The strength will be indicated by the deflection...(View More) of magnetic compass needles and by the distance a coil of wire was moved by the action of the circuit. This activity requires coils or spools of wire, a knife switch, three magnetic compasses, a source of electricity such as 3 D-cell batteries or an AC to DC power adapter, alligator-clipped wire, and a bar or cow magnet. This is the fourth lesson in the second session of the Exploring Magnetism teachers guide.(View Less)

This is an activity about electromagnetism. Learners will use a compass to map the magnetic field lines surrounding a coil of wire that is connected to a battery. This activity requires a large coil or spool of wire, a source of electricity such as...(View More) 3 D-cell batteries or an AC to DC power adapter, alligator-clipped wire, and magnetic compasses. This is the third lesson in the second session of the Exploring Magnetism teachers guide.(View Less)
